Thomas Heller74d36f02006-08-04 18:17:40 +000015- On Windows, the PyErr_Warn function is now exported from
16 the Python dll again.
17
Neal Norwitz4ffedad2006-08-04 04:58:47 +000018- Bug #1191458: tracing over for loops now produces a line event
19 on each iteration. Fixing this problem required changing the .pyc
20 magic number. This means that .pyc files generated before 2.5c1
21 will be regenerated.
22
Neal Norwitz0cbd8052006-08-04 05:09:28 +000023- Bug #1333982: string/number constants were inappropriately stored
24 in the byte code and co_consts even if they were not used, ie
25 immediately popped off the stack.
26
Georg Brandle9462c72006-08-04 18:03:37 +000027- Fixed a reference-counting problem in property().

Fred Drake53912162006-07-29 13:22:49 +000060What's New in Python 2.5 beta 3?
61================================
Neal Norwitza1f10902006-07-12 07:28:29 +000062
Anthony Baxter5d32a9f2006-08-02 07:43:09 +000063*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +000064
65Core and builtins
66-----------------
67
Neal Norwitzc5e060d2006-08-02 06:14:22 +000068- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t, it previously
69 returned a long (see PEP 353).
70
Neal Norwitzf71ec5a2006-07-30 06:57:04 +000071- Bug #1515471: string.replace() accepts character buffers again.
72
Neal Norwitz07aadb12006-07-30 06:55:48 +000073- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
74 This provides the proper warning for struct.pack().
75 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
76
Neal Norwitz0d62a062006-07-30 06:53:31 +000077- Patch #1531113: Fix augmented assignment with yield expressions.
78 Also fix a SystemError when trying to assign to yield expressions.
79
Phillip J. Ebyf7575d02006-07-28 21:12:07 +000080- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
81 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
82 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
83 excessive filesystem operations during imports.
84
Tim Petersbc24eee2006-07-27 01:14:53 +000085- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
86 operations on signed longs that are formally undefined by C.
87 Unfortunately, at least one compiler now cares about that, so complicated
88 the code to make that compiler happy again.
89
Martin v. Löwis982e9fe2006-07-24 12:54:17 +000090- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
91
Martin v. Löwisd22968a2006-07-24 11:54:53 +000092- Patch #1232023: Stop including current directory in search
93 path on Windows.
94
Neal Norwitze1fdb322006-07-21 05:32:28 +000095- Fix some potential crashes found with failmalloc.
96
Neal Norwitze7563102006-07-17 01:00:16 +000097- Fix warnings reported by Klocwork's static analysis tool.
98
Neal Norwitz84be93b2006-07-16 01:50:38 +000099- Bug #1512814, Fix incorrect lineno's when code within a function
100 had more than 255 blank lines.
101
Georg Brandl9dceedb2006-07-12 15:31:17 +0000102- Patch #1521179: Python now accepts the standard options ``--help`` and
103 ``--version`` as well as ``/?`` on Windows.
104
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000105- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000106 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000107 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000108
Tim Peters112aad32006-07-19 00:03:19 +0000109- Bug #1524317: Compiling Python ``--without-threads`` failed.
110 The Python core compiles again then, and, in a build without threads, the
111 new ``sys._current_frames()`` returns a dictionary with one entry,
112 mapping the faux "thread id" 0 to the current frame.
113
Ronald Oussoren3075e162006-07-25 20:28:55 +0000114- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000115
Ronald Oussoren3075e162006-07-25 20:28:55 +0000116
Neal Norwitza1f10902006-07-12 07:28:29 +0000117Library
118-------
119
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000120- Correction of patch #1455898: In the mbcs decoder, set final=False
121 for stream decoder, but final=True for the decode function.
122
Georg Brandl07fec3a2006-08-01 18:49:24 +0000123- os.urandom no longer masks unrelated exceptions like SystemExit or
124 KeyboardInterrupt.
125
Martin v. Löwis4e678382006-07-30 13:00:31 +0000126- Bug #1525866: Don't copy directory stat times in
127 shutil.copytree on Windows
128
Georg Brandle34ac7c2006-07-30 11:07:23 +0000129- Bug #1002398: The documentation for os.path.sameopenfile now correctly
130 refers to file descriptors, not file objects.
131
Fred Drakefbdeaad2006-07-29 16:56:15 +0000132- Rename of the xml package to xmlcore, and the import hackery done to
133 make it appear at both names, has been removed. Bug #1511497,
134 #1513611, and probably others.
135
Georg Brandledd9b0d2006-07-29 09:33:26 +0000136- Bug #1441397: The compiler module now recognizes module and function
137 docstrings correctly as it did in Python 2.4.
138
Tim Peters6f681472006-07-27 23:44:37 +0000139- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
140 lost that tests are sorted by name before being run. This rarely
141 matters for well-written tests, but can create baffling symptoms if
142 side effects from one test to the next affect outcomes. ``DocTestFinder``
143 has been changed to sort the list of tests it returns.
144
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000145- The distutils version has been changed to 2.5.0, and are now kept
146 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000147
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000148- Bug #978833: Really close underlying socket in _socketobject.close.
149
Georg Brandl0619a322006-07-26 07:40:17 +0000150- Bug #1459963: urllib and urllib2 now normalize HTTP header names correctly
151 with title().
152
Georg Brandlcf0c1722006-07-26 07:23:32 +0000153- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
154 to recursive calls and call it with the failing package name.
155
Martin v. Löwis0b483032006-07-25 09:53:12 +0000156- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
157
Georg Brandlc13c34c2006-07-24 14:09:56 +0000158- Patch #1515343: Fix printing of deprecated string exceptions with a
159 value in the traceback module.
160
Greg Ward48fae7a2006-07-23 16:05:51 +0000161- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
162
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000163- Patch #1524429: Use repr() instead of backticks in Tkinter again.
164
Brett Cannoncaebe222006-07-18 04:41:36 +0000165- Bug #1520914: Change time.strftime() to accept a zero for any position in its
166 argument tuple. For arguments where zero is illegal, the value is forced to
167 the minimum value that is correct. This is to support an undocumented but
168 common way people used to fill in inconsequential information in the time
169 tuple pre-2.4.
170
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000171- Patch #1220874: Update the binhex module for Mach-O.
172
Barry Warsawb110bad2006-07-21 14:51:07 +0000173- The email package has improved RFC 2231 support, specifically for
174 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
175 (name*0=<blah>) parameter continuations. This may change the types of
176 values returned from email.message.Message.get_param() and friends.
177 Specifically in some cases where non-encoded continuations were used,
178 get_param() used to return a 3-tuple of (None, None, string) whereas now it
179 will just return the string (since non-encoded continuations don't have
180 charset and language parts).
181
182 Also, whereas % values were decoded in all parameter continuations, they are
183 now only decoded in encoded parameter parts.
184
Ronald Oussoren3075e162006-07-25 20:28:55 +0000185- Bug #1517990: IDLE keybindings on MacOS X now work correctly
186
187- Bug #1517996: IDLE now longer shows the default Tk menu when a
188 path browser, class browser or debugger is the frontmost window on MacOS X
189
Barry Warsaw00decd72006-07-27 23:43:15 +0000190- Patch #1520294: Support for getset and member descriptors in types.py,
191 inspect.py, and pydoc.py. Specifically, this allows for querying the type
192 of an object against these built-in types and more importantly, for getting
193 their docstrings printed in the interactive interpreter's help() function.

197-----------------
198
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000199- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
200 a socket operation on a socket with a timeout, the exception will be
201 caught correctly. Previously, the exception was not caught.
202
Thomas Heller1393d6a2006-07-28 21:43:20 +0000203- Patch #1529514: The _ctypes extension is now compiled on more
204 openbsd target platforms.
205
Tim Peters9cab5932006-07-28 00:30:00 +0000206- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
207 a memory leak, affecting pickles and deep copies.
208
Tim Petersbc24eee2006-07-27 01:14:53 +0000209- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000210 Paul Eggert.
211
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000212- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
213
Thomas Hellerce049a02006-07-14 17:51:14 +0000214- Patch #1521817: Index range checking on ctypes arrays containing
215 exactly one element enabled again. This allows iterating over these
216 arrays, without the need to check the array size before.
217
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000218- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000219 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000220 /dev/null in certain cases; this is now fixed.
221
Thomas Heller47d7a062006-07-12 08:43:47 +0000222- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
223 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000224
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000225- Because of a misspelled preprocessor symbol, ctypes was always
226 compiled without thread support; this is now fixed.
227
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000228- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
229 methods now allow their database parameter to be None as the
230 sleepycat API allows.
231
Matt Flemingec926502006-07-28 11:27:27 +0000232- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
233 bluetooth API compared with Linux and FreeBSD.
234
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000235Tests
236-----
237
238- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
239 how long the test file should take to play. Now accepts taking 2.93 secs
240 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
241
Georg Brandl4793aa32006-07-28 18:31:39 +0000242- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
243 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
244 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000251Mac
252---
253
254- PythonLauncher now works correctly when the path to the script contains
255 characters that are treated specially by the shell (such as quotes).
256
257- Bug #1527397: PythonLauncher now launches scripts with the working directory
258 set to the directory that contains the script instead of the user home
259 directory. That latter was an implementation accident and not what users
260 expect.

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000271- Bug #1441486: The literal representation of -(sys.maxint - 1)
272 again evaluates to a int object, not a long.
273
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000274- Bug #1501934: The scope of global variables that are locally assigned
275 using augmented assignment is now correctly determined.
276
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000277- Bug #927248: Recursive method-wrapper objects can now safely

279
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000280- Bug #1417699: Reject locale-specific decimal point in float()
281 and atof().
282
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000283- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
284 omit a default "error" argument for NULL pointer. This allows
285 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000286
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000287- Bug #1519018: 'as' is now validated properly in import statements.
288
Neal Norwitz28746ab2006-07-09 22:14:42 +0000289- On 64 bit systems, int literals that use less than 64 bits are
290 now ints rather than longs.
291
Neal Norwitzed657552006-07-10 00:04:44 +0000292- Bug #1512814, Fix incorrect lineno's when code at module scope
293 started after line 256.
294
Tim Peters32a83612006-07-10 21:08:24 +0000295- New function ``sys._current_frames()`` returns a dict mapping thread
296 id to topmost thread stack frame. This is for expert use, and is
297 especially useful for debugging application deadlocks. The functionality
298 was previously available in Fazal Majid's ``threadframe`` extension
299 module, but it wasn't possible to do this in a wholly threadsafe way from
300 an extension.

Thomas Woutersadd19112006-07-05 11:03:49 +0000318- string.Template() now correctly handles tuple-values. Previously,
319 multi-value tuples would raise an exception and single-value tuples would
320 be treated as the value they contain, instead.
321
Martin v. Löwisede77f52006-07-03 13:01:35 +0000322- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

347
Brett Cannon53ab5b72006-06-22 16:49:14 +0000348- Bug #1510580: The 'warnings' module improperly required that a Warning
349 category be either a types.ClassType and a subclass of Warning. The proper
350 check is just that it is a subclass with Warning as the documentation states.
351
Georg Brandlad29e632006-06-21 17:45:17 +0000352- The compiler module now correctly compiles the new try-except-finally
353 statement (bug #1509132).
354
Neal Norwitz60373cd2006-06-22 06:30:50 +0000355- The wsgiref package is now installed properly on Unix.
356
Vinay Sajip28e57612006-07-01 10:45:20 +0000357- A bug was fixed in logging.config.fileConfig() which caused a crash on
358 shutdown when fileConfig() was called multiple times.
359
Gerhard Häring762fbd32006-07-02 17:48:30 +0000360- The sqlite3 module did cut off data from the SQLite database at the first
361 null character before sending it to a custom converter. This has been fixed
362 now.

365-----------------
366
Tim Peters112aad32006-07-19 00:03:19 +0000367- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
368 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
369 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000370
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000371- Assigning None to pointer type fields in ctypes structures possible
372 overwrote the wrong fields, this is fixed now.
373
374- Fixed a segfault in _ctypes when ctypes.wintypes were imported
375 on non-Windows platforms.
376
377- Bug #1518190: The ctypes.c_void_p constructor now accepts any
378 integer or long, without range checking.
379
380- Patch #1517790: It is now possible to use custom objects in the ctypes
381 foreign function argtypes sequence as long as they provide a from_param
382 method, no longer is it required that the object is a ctypes type.
383
384- The '_ctypes' extension module now works when Python is configured
385 with the --without-threads option.
386
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000387- Bug #1513646: os.access on Windows now correctly determines write
388 access, again.
389
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000390- Bug #1512695: cPickle.loads could crash if it was interrupted with
391 a KeyboardInterrupt.
392
Neal Norwitza12aa882006-07-06 06:45:08 +0000393- Bug #1296433: parsing XML with a non-default encoding and
394 a CharacterDataHandler could crash the interpreter in pyexpat.
395

402
Tim Peters32a83612006-07-10 21:08:24 +0000403- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000404 Previously, the slight difference could cause compilation errors of the
405 'zlib' module on systems with more than one version of zlib.
406
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000407- The MSI compileall step was fixed to also support a TARGETDIR
408 with spaces in it.
409

437Core and builtins
438-----------------
439
Georg Brandla56b9152006-06-19 06:35:54 +0000440- Patch #1507676: Error messages returned by invalid abstract object operations
441 (such as iterating over an integer) have been improved and now include the
442 type of the offending object to help with debugging.
443
Brett Cannonea3912b2006-06-13 21:46:41 +0000444- Bug #992017: A classic class that defined a __coerce__() method that returned
445 its arguments swapped would infinitely recurse and segfault the interpreter.
446
Neal Norwitz909eb122006-06-12 02:13:21 +0000447- Fix the socket tests so they can be run concurrently.
448
Neal Norwitzb9845e72006-06-12 02:11:18 +0000449- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000450 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000451
Brett Cannon22565aa2006-06-09 22:31:23 +0000452- Bug #532646: object.__call__() will continue looking for the __call__
453 attribute on objects until one without one is found. This leads to recursion
454 when you take a class and set its __call__ attribute to an instance of the
455 class. Originally fixed for classic classes, but this fix is for new-style.
456 Removes the infinite_rec_3 crasher.
457
Georg Brandl24250812006-06-09 18:45:48 +0000458- The string and unicode methods startswith() and endswith() now accept
459 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
460
Brett Cannonde3b0522006-06-08 17:00:45 +0000461- Buffer objects, at the C level, never used the char buffer
462 implementation even when the char buffer for the wrapped object was
463 explicitly requested (originally returned the read or write buffer).
464 Now a TypeError is raised if the char buffer is not present but is
465 requested.
466
Georg Brandlddbaa662006-06-04 21:56:52 +0000467- Patch #1346214: Statements like "if 0: suite" are now again optimized
468 away like they were in Python 2.4.
469
Georg Brandlb7c8f542006-05-27 12:30:25 +0000470- Builtin exceptions are now full-blown new-style classes instead of
471 instances pretending to be classes, which speeds up exception handling
472 by about 80% in comparison to 2.5a2.
473
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000474- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
475 Unicode 4.1.
476
Georg Brandlf4ef1162006-05-26 18:03:31 +0000477- Patch #921466: sys.path_importer_cache is now used to cache valid and
478 invalid file paths for the built-in import machinery which leads to
479 fewer open calls on startup.
480
Tim Peters696cf432006-05-24 21:10:40 +0000481- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
482 of-2 bases. The largest speedup is for inputs with about 1000 decimal
483 digits. Conversion from non-power-of-2 bases remains quadratic-time in
484 the number of input digits (it was and remains linear-time for bases
485 2, 4, 8, 16 and 32).
486
Tim Petersb713ec22006-05-23 18:45:30 +0000487- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
488 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
489 an integer close to ``sys.maxint``. This was repaired by patch
490 #1335972, which also gives a nice speedup.
491
Richard Jonescebbefc2006-05-23 18:28:17 +0000492- Patch #1337051: reduced size of frame objects.
493
494- PyErr_NewException now accepts a tuple of base classes as its
495 "base" parameter.
496
Richard Jones7c88dcc2006-05-23 10:37:38 +0000497- Patch #876206: function call speedup by retaining allocated frame
498 objects.
499
Georg Brandl7b90e162006-05-18 07:01:27 +0000500- Bug #1462152: file() now checks more thoroughly for invalid mode
501 strings and removes a possible "U" before passing the mode to the
502 C library function.
503
Neal Norwitz1004a532006-05-15 07:17:23 +0000504- Patch #1488312, Fix memory alignment problem on SPARC in unicode
505
Neal Norwitz373f0a72006-05-15 07:04:36 +0000506- Bug #1487966: Fix SystemError with conditional expression in assignment
507
Martin v. Löwis879768d2006-05-11 13:28:43 +0000508- WindowsError now has two error code attributes: errno, which carries
509 the error values from errno.h, and winerror, which carries the error
510 values from winerror.h. Previous versions put the winerror.h values
511 (from GetLastError()) into the errno attribute.
512
Martin v. Löwis77736712006-05-04 05:51:03 +0000513- Patch #1475845: Raise IndentationError for unexpected indent.
514
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000515- Patch #1479181: split open() and file() from being aliases for each other.
516
Tim Peters44bd9862006-06-01 13:49:23 +0000517- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
518 methods were always silently ignored by dictionaries when comparing keys.
519 They are now passed through (except when using the C API function
520 ``PyDict_GetItem()``, whose semantics did not change).
521
522- Bug #1456209: In some obscure cases it was possible for a class with a
523 custom ``__eq__()`` method to confuse dict internals when class instances
524 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
525 No, you don't have any code that did this ;-)

533
Brett Cannon6ee7d012006-06-08 16:23:04 +0000534- Change binascii.hexlify to accept a read-only buffer instead of only a char
535 buffer and actually follow its documentation.
536
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000537- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
538
Nick Coghlanc649ec52006-05-29 12:43:05 +0000539- Patch #1478788 (modified version): The functional extension module has
540 been renamed to _functools and a functools Python wrapper module added.
541 This provides a home for additional function related utilities that are
542 not specifically about functional programming. See PEP 309.
543
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000544- Patch #1493701: performance enhancements for struct module.

552 enabled builds on Windows and systems with Posix threads support.
553
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000554- On Win32, os.listdir now supports arbitrarily-long Unicode path names
555 (up to the system limit of 32K characters).
556
557- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
558 As a result, these functions now raise WindowsError instead of OSError.
559
Tim Peters7a822da2006-05-25 21:50:17 +0000560- ``time.clock()`` on Win64 should use the high-performance Windows
561 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
562 Windows platforms).
563
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000564- Calling Tk_Init twice is refused if the first call failed as that
565 may deadlock.
566
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000567- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
568 accept it without potentially using an uninitialized pointer.
569
570- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods

583
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000584- bsddb: the bsddb.dbtables Modify method now raises the proper error and

Gregory P. Smith506f7b52006-06-15 08:52:32 +0000588- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +0000589 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000590 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
591 database calls that would previously deadlock. [SF python bug #775414]

621 double-byte encodings.
622
Tim Peters43898b42006-06-14 04:09:25 +0000623- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
624 guarantee that adjacent triples in the return list always describe
625 non-adjacent blocks. Previously, a pair of matching blocks could end
626 up being described by multiple adjacent triples that formed a partition
627 of the matching pair.
628
Greg Ward0e0c9f42006-06-11 16:24:11 +0000629- Bug #1498146: fix optparse to handle Unicode strings in option help,
630 description, and epilog.
631
Greg Wardd1c797e2006-06-11 14:42:41 +0000632- Bug #1366250: minor optparse documentation error.
633
Greg Ward7f547402006-06-11 00:40:49 +0000634- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
635 clarify docs.
636
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000637- The wsgiref package has been added to the standard library.
638
Nick Coghlan676725d2006-06-08 13:54:49 +0000639- The functions update_wrapper() and wraps() have been added to the functools
640 module. These make it easier to copy relevant metadata from the original
641 function when writing wrapper functions.
642
Tim Petersd6a9eef2006-06-05 01:48:21 +0000643- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
644 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000645
Martin v. Löwis3f767792006-06-04 19:36:28 +0000646- Patch #1359618: Speed up charmap encoder by using a trie structure
647 for lookup.
648
Tim Petersd609b1a2006-06-02 23:22:51 +0000649- The functions in the ``pprint`` module now sort dictionaries by key
650 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
651 if and only if its display required more than one line, although that
652 wasn't documented. The new behavior increases predictability; e.g.,
653 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
654
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000655- Patch #1497027: try HTTP digest auth before basic auth in urllib2
656 (thanks for J. J. Lee).
657
Georg Brandl2b330372006-05-28 20:23:12 +0000658- Patch #1496206: improve urllib2 handling of passwords with respect to
659 default HTTP and HTTPS ports.
660
George Yoshidaf3c65de2006-05-28 16:39:09 +0000661- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
662
Bob Ippolito7298f272006-05-23 18:43:47 +0000663- Patch #1281707: speed up gzip.readline.
664
Georg Brandlb89316f2006-05-17 15:51:16 +0000665- Patch #1180296: Two new functions were added to the locale module:
666 format_string() to get the effect of "format % items" but locale-aware,
667 and currency() to format a monetary number with currency sign.
668
Georg Brandle3a25832006-05-17 14:56:04 +0000669- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
670 and several features added, such as speed and geometry control.
671
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000672- Patch #1488881: add support for external file objects in bz2 compressed
673 tarfiles.
674
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000675- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
676 stdout arguments, making it possible to redirect input and output
677 for remote debugging.
678
679- Patch #1484695: Update the tarfile module to version 0.8. This fixes
680 a couple of issues, notably handling of long file names using the
681 GNU LONGNAME extension.
682
683- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
684 new flag when ``name`` is already the name of an option flag.
685
686- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
687 package.
688
689- Patch #1472854: make the rlcompleter.Completer class usable on non-
690 UNIX platforms.
691
692- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
693
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000694- Bug #1472827: correctly escape newlines and tabs in attribute values in
695 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000725What's New in Python 2.5 alpha 2?
726=================================
727
728*Release date: 27-APR-2006*
729
730Core and builtins
731-----------------
732
Thomas Heller1b046642006-04-18 18:51:06 +0000733- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
734 by converting these apis from macros into exported functions again:
735
736 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
737 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
738 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
739 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
740 PyRun_String Py_CompileString
741
Martin v. Löwis45294a92006-04-18 06:24:08 +0000742- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
743
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000744- All uses of PyStructSequence_InitType have been changed to initialize
745 the type objects only once, even if the interpreter is initialized
746 multiple times.
747
Neal Norwitz61546162006-04-14 05:20:28 +0000748- Bug #1454485, array.array('u') could crash the interpreter. This was
749 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
750 to unicode when it didn't make sense. 'u#' now requires a unicode string.
751
752- Py_UNICODE is unsigned. It was always documented as unsigned, but
753 due to a bug had a signed value in previous versions.
754
Tim Peters3a5e8b12006-04-11 01:44:07 +0000755- Patch #837242: ``id()`` of any Python object always gives a positive
756 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
757 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000758 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000759 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000760
Tim Peters3a5e8b12006-04-11 01:44:07 +0000761 def __hash__(self):
762 return id(self) # WRONG
763
764 because a hash result must be a (short) Python int but it was always
765 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000766 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000767 was always usable as a hash value before this patch. That's no longer
768 necessarily so.
769
770- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000771 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000772 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000773 #1454844)
774
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000775- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
776 involving generators that have paused outside of any ``try`` or ``with``
777 blocks. (In 2.5a1, a paused generator that was part of a reference
778 cycle could not be garbage collected, regardless of whether it was
779 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000781Extension Modules

785 is a macro.
786
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000787- Bug #1467952: os.listdir() now correctly raises an error if readdir()
788 fails with an error condition.
789
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000790- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
791
792- Bug #1117761: bsddb.*open() no longer raises an exception when using
793 the cachesize parameter.
794
795- Bug #1149413: bsddb.*open() no longer raises an exception when using
796 a temporary db (file=None) with the 'n' flag to truncate on open.
797
798- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
799 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000800
Armin Rigoa9017c32006-04-19 11:50:27 +0000801- Patch #1062014: AF_UNIX sockets under Linux have a special
802 abstract namespace that is now fully supported.

805-------
806
Peter Astrand7d1d4362006-07-14 14:04:45 +0000807- Bug #1223937: subprocess.CalledProcessError reports the exit status
808 of the process using the returncode attribute, instead of
809 abusing errno.
810
Tim Peters711bf302006-04-25 03:31:36 +0000811- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
812 a doctest to be skipped (the code is not run, and the expected output
813 or exception is ignored).
814
Nick Coghlanda2268f2006-04-24 04:37:15 +0000815- Fixed contextlib.nested to cope with exceptions being raised and
816 caught inside exit handlers.
817
Greg Wardab05edc2006-04-23 03:47:58 +0000818- Updated optparse module to Optik 1.5.1 (allow numeric constants in
819 hex, octal, or binary; add ``append_const`` action; keep going if
820 gettext cannot be imported; added ``OptionParser.destroy()`` method;
821 added ``epilog`` for better help generation).
822
Tim Peters21fbd572006-04-21 21:18:10 +0000823- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
824 called from a thread spawned as a side effect of importing a module.
825
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000826- The pydoc module now supports documenting packages contained in
827 .zip or .egg files.
828
829- The pkgutil module now has several new utility functions, such
830 as ``walk_packages()`` to support working with packages that are either
831 in the filesystem or zip files.
832
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000833- The mailbox module can now modify and delete messages from
834 mailboxes, in addition to simply reading them. Thanks to Gregory
835 K. Johnson for writing the code, and to the 2005 Google Summer of
836 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000837
Tim Petersc7605f22006-04-17 21:12:33 +0000838- The ``__del__`` method of class ``local`` in module ``_threading_local``
839 returned before accomplishing any of its intended cleanup.
840
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000841- Patch #790710: Add breakpoint command lists in pdb.
842
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000843- Patch #1063914: Add Tkinter.Misc.clipboard_get().

846
Anthony Baxtere29002c2006-04-12 12:07:31 +0000847- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
848 Windows. Bug #1469163.
849
Phillip J. Eby47032112006-04-11 01:07:43 +0000850- The warnings, linecache, inspect, traceback, site, and doctest modules
851 were updated to work correctly with modules imported from zipfiles or
852 via other PEP 302 __loader__ objects.
853
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000854- Patch #1467770: Reduce usage of subprocess._active to processes which
855 the application hasn't waited on.
856

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000874- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
875 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000876 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000877 CXX from --with-cxx-main, see description in README.
878
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000879- Patch #1429775: Link extension modules with the shared libpython.

889
Nick Coghlanda2268f2006-04-24 04:37:15 +0000890- test_contextlib now checks contextlib.nested can cope with exceptions
891 being raised and caught inside exit handlers.
892
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000893- test_cmd_line now checks operation of the -m and -c command switches
894
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000895- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
896 it separately and by hand. It also wasn't cleaning up its changes to
897 the current Decimal context.
898
Thomas Woutersabd08882006-04-26 15:53:30 +0000899- regrtest.py now has a -M option to run tests that test the new limits of
900 containers, on 64-bit architectures. Running these tests is only sensible
901 on 64-bit machines with more than two gigabytes of memory. The argument
902 passed is the maximum amount of memory for the tests to use.

911-------------
912
Tim Petersb06d28c2006-05-12 01:57:59 +0000913- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.

930
Nick Coghlan43832302006-04-23 17:04:07 +0000931- PEP 338: -m command line switch now delegates to runpy.run_module
932 allowing it to support modules in packages and zipfiles
933
Martin v. Löwisc661b882006-04-20 04:54:23 +0000934- On Windows, .DLL is not an accepted file name extension for
935 extension modules anymore; extensions are only found if they
936 end in .PYD.
937
Martin v. Löwisea62d252006-04-03 10:56:49 +0000938- Bug #1421664: sys.stderr.encoding is now set to the same value as
939 sys.stdout.encoding.

Neal Norwitze98ccf62006-03-23 05:39:47 +0000950- Bug #1115379: Compiling a Unicode string with an encoding declaration
951 now gives a SyntaxError.
952
Georg Brandlabd1ff82006-03-18 07:59:59 +0000953- Previously, Python code had no easy way to access the contents of a
954 cell object. Now, a ``cell_contents`` attribute has been added
955 (closes patch #1170323).
956
Tim Peterscf79aac2006-03-16 01:14:46 +0000957- Patch #1123430: Python's small-object allocator now returns an arena to
958 the system ``free()`` when all memory within an arena becomes unused
959 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
960 freed. Some applications will see a drop in virtual memory size now,
961 especially long-running applications that, from time to time, temporarily
962 use a large number of small objects. Note that when Python returns an
963 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000964 platform C library will in turn return that memory to the operating system.
965 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000966 appears to be effective at least on Microsoft C and gcc-based systems.
967 Thanks to Evan Jones for hard work and patience.
968
Georg Brandl533ff6f2006-03-08 18:09:27 +0000969- Patch #1434038: property() now uses the getter's docstring if there is
970 no "doc" argument given. This makes it possible to legitimately use
971 property() as a decorator to produce a read-only property.
972
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000973- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
974 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
975 of requiring an int or long in slicing and a few other contexts, enabling
976 other objects (e.g. Numeric Python's integers) to be used as slice indices.
977
Neal Norwitz995acdf2006-03-07 05:01:00 +0000978- Fixed various bugs reported by Coverity's Prevent tool.
979
Brett Cannonbf364092006-03-01 04:25:17 +0000980- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
981 new exception base class, BaseException, which has a new message attribute.
982 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
983 Raising a string exception now raises a DeprecationWarning.
984
Thomas Woutersfb609f42006-02-28 16:37:25 +0000985- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
986 explicitly relative, using 'from .module import name' to mean 'from the same
987 package as this module is in. Imports without dots still default to the
988 old relative-then-absolute, unless 'from __future__ import
989 absolute_import' is used.
990
Brett Cannona7446e32006-02-27 23:39:10 +0000991- Properly check if 'warnings' raises an exception (usually when a filter set
992 to "error" is triggered) when raising a warning for raising string
993 exceptions.
994
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000995- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000996 The name was removed from Include/code.h.
997
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000998- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000999
Guido van Rossum1968ad32006-02-25 22:38:04 +00001000- Patch 1433928:
1001 - The copy module now "copies" function objects (as atomic objects).
1002 - dict.__getitem__ now looks for a __missing__ hook before raising
1003 KeyError.
1004
Tim Peters84ef21c2006-02-28 20:39:06 +00001005- PEP 343: with statement implemented. Needs ``from __future__ import
1006 with_statement``. Use of 'with' as a variable will generate a warning.
1007 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001008 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001009 The following objects have __context__ methods:
1010 - The built-in file type.
1011 - The thread.LockType type.
1012 - The following types defined by the threading module:
1013 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1014 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001015
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001016- Fix the encodings package codec search function to only search
1017 inside its own package. Fixes problem reported in patch #1433198.
1018
1019 Note: Codec packages should implement and register their own
1020 codec search function. PEP 100 has the details.
1021
Tim Peters9ea89d22006-06-04 03:26:02 +00001022- PEP 353: Using ``Py_ssize_t`` as the index type.
1023
1024- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1025 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1026 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1027 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1028 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001029
Neal Norwitzfc76d632006-01-10 06:03:13 +00001030- Patch #1400181, fix unicode string formatting to not use the locale.
1031 This is how string objects work. u'%f' could use , instead of .
1032 for the decimal point. Now both strings and unicode always use periods.
1033
Neal Norwitz671b9e32006-01-09 07:07:12 +00001034- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1035 configure would break checking curses.h.
1036
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001037- Bug #959576: The pwd module is now builtin. This allows Python to be
1038 built on UNIX platforms without $HOME set.
1039
Neal Norwitzc10978f2005-12-19 06:07:16 +00001040- Bug #1072182, fix some potential problems if characters are signed.
1041
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001042- Bug #889500, fix line number on SyntaxWarning for global declarations.
1043
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001044- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1045
Neal Norwitze7214a12005-12-18 05:03:17 +00001046- Support for converting hex strings to floats no longer works.
1047 This was not portable. float('0x3') now raises a ValueError.
1048
Barry Warsaw2a38a862005-12-18 01:27:35 +00001049- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001050 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001051 is now displayed in interactive prompt banner.
1052
Georg Brandlfa166682005-12-17 21:45:17 +00001053- Implementation of PEP 341 - Unification of try/except and try/finally.
1054 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001055 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001056
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001057- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1058 now encodes backslash correctly.
1059
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001060- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1061
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001062- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001063 and long longs.
1064
Neal Norwitz67715f02005-11-09 06:59:35 +00001065- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001066 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001067 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001068
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001069- Replaced most Unicode charmap codecs with new ones using the
1070 new Unicode translate string feature in the builtin charmap
1071 codec; the codecs were created from the mapping tables available
1072 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1073 encodings now include a mapping for the Apple logo)
1074
Tim Peterse3547fd2005-12-16 23:13:57 +00001075- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001076
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001077- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001078
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001079- A new AST parser implementation was completed. The abstract
1080 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001081 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001082
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001083- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001084 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1085
Neal Norwitz708e51a2005-10-03 04:48:15 +00001086- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1087
Neal Norwitz11bd1192005-10-03 00:54:56 +00001088- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1089 Provide a warning when a directory is passed on the command line.
1090
Neal Norwitz40d37812005-10-02 01:48:49 +00001091- Fix segfault with invalid coding.
1092
1093- SF bug #772896: unknown encoding results in MemoryError.
1094
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001095- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001096 supported a __len__() method which evaluated to False when the iterator
1097 was empty.
1098
Guido van Rossum630db602005-09-20 18:49:54 +00001099- On 64-bit platforms, when __len__() returns a value that cannot be
1100 represented as a C int, raise OverflowError.
1101
Skip Montanarof8948ca2005-09-19 03:54:46 +00001102- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001103 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001104
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001105- SF bug #893549: parsing keyword arguments was broken with a few format
1106 codes.
1107
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001108- Changes donated by Elemental Security to make it work on AIX 5.3
1109 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1110 bug #105470: test_pwd fails on 64bit system (Opteron).
1111
Guido van Rossum539c6622005-09-14 17:49:54 +00001112- Changes donated by Elemental Security to make it work on HP-UX 11 on
1113 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1114
Georg Brandl4550b8d2005-08-26 06:43:52 +00001115- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001116 (fixes bug #1119418).
1117
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001118- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1119
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001120- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1121 exceptions that cause a function to exit.
1122
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001123- The implementation of set() and frozenset() was revised to use its
1124 own internal data structure. Memory consumption is reduced by 1/3
1125 and there are modest speed-ups as well. The API is unchanged.
1126
Tim Petersde7990b2005-07-17 23:45:23 +00001127- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1128
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001129- SF bug #1229429: PyObject_CallMethod failed to decrement some
1130 reference counts in some error exit cases.
1131
Tim Petersecc6e6a2005-07-10 22:30:55 +00001132- SF bug #1185883: Python's small-object memory allocator took over
1133 a block managed by the platform C library whenever a realloc specified
1134 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001135 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001136 portable way to copy data from the C-managed block into Python's
1137 small-object space without risking a memory fault. Python's small-object
1138 realloc now leaves such blocks under the control of the platform C
1139 realloc.
1140
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001141- SF bug #1232517: An overflow error was not detected properly when
1142 attempting to convert a large float to an int in os.utime().
1143
Raymond Hettinger3296e692005-06-29 23:29:56 +00001144- SF bug #1224347: hex longs now print with lowercase letters just
1145 like their int counterparts.
1146
Michael W. Hudson188d4362005-06-20 16:52:57 +00001147- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1148 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1149 interpreter states; back out that fix and do a better job (see
1150 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1151 for a longer write-up of the problem).
1152
Michael W. Hudsondf888462005-06-03 14:41:55 +00001153- SF patch #1180995: marshal now uses a binary format by default when
1154 serializing floats.
1155
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001156- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1157 the routines that promise to produce IEEE 754 binary representations
1158 of floats now simply copy bytes around.
1159
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001160- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1161 278.
1162
Brett Cannonc3647ac2005-04-26 03:45:26 +00001163- patch #1109424: int, long, float, complex, and unicode now check for the
1164 proper magic slot for type conversions when subclassed. Previously the
1165 magic slot was ignored during conversion. Semantics now match the way
1166 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001167 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001168 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001169 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001170
Barry Warsawc8d907c2005-04-19 23:43:40 +00001171- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1172 NULL, now raise an AttributeError when attempting to set or delete the
1173 attribute. Previously a TypeError was raised, but this was inconsistent
1174 with the equivalent pure-Python implementation.
1175
Michael W. Hudson774479c2005-04-18 08:46:17 +00001176- It is now safe to call PyGILState_Release() before
1177 PyEval_InitThreads() (note that if there is reason to believe there
1178 are multiple threads around you still must call PyEval_InitThreads()
1179 before using the Python API; this fix is for extension modules that
1180 have no way of knowing if Python is multi-threaded yet).
1181
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001182- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1183 disabled caused a crash.
1184
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001185- Bug #1165306: instancemethod_new allowed the creation of a method
1186 with im_class == im_self == NULL, which caused a crash when called.
1187
Tim Petersecc6e6a2005-07-10 22:30:55 +00001188- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001189 fixes the crash seen in bug #1165761
1190
Raymond Hettinger96229b12005-03-11 06:49:40 +00001191- Added two new builtins, any() and all().
1192
Brett Cannon409d8f22005-03-05 06:47:57 +00001193- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001194 (e.g., ``class C(): pass`` is no longer a syntax error).
1195 Patch #1176012 added support to the 'parser' module and 'compiler' package
1196 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001197
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001198- Patch #1115086: Support PY_LONGLONG in structmember.
1199
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001200- Bug #1155938: new style classes did not check that __init__() was
1201 returning None.
1202
Tim Petersecc6e6a2005-07-10 22:30:55 +00001203- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001204 ('\') with a specific error message.
1205
Martin v. Löwisff232d72005-03-03 09:24:38 +00001206- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1207
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001208- Bug #1124295: the __name__ attribute of file objects was
1209 inadvertently made inaccessible in restricted mode.
1210
Tim Petersecc6e6a2005-07-10 22:30:55 +00001211- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001212 an ferror() call.
1213

1215 list.sort().
1216
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001217- The peephole optimizer now performs simple constant folding in expressions:
1218 (2+3) --> (5).

Neil Schemenauercf52c072005-08-12 17:34:58 +00001229- Change the %s format specifier for str objects so that it returns a
1230 unicode instance if the argument is not an instance of basestring and
1231 calling __str__ on the argument returns a unicode instance.
1232
Tim Petersf4e69282006-02-27 17:15:31 +00001233- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1234 current thread state when the auto-GIL-state machinery knows about
1235 it (since the thread state is being deleted, continuing to remember it
1236 can't help, but can hurt if another thread happens to get created with
1237 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001429- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1430 been renamed to have only a single underscore prefix. This was done to
1431 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001432
Nick Coghlan43832302006-04-23 17:04:07 +00001433- PEP 338: new module runpy defines a run_module function to support
1434 executing modules which provide access to source code or a code object
1435 via the PEP 302 import mechanisms.
1436
Anthony Baxter93f5b932006-04-03 08:05:07 +00001437- The email module's parsedate_tz function now sets the daylight savings

1445 in attribute values.
1446
Anthony Baxterc51ee692006-04-01 00:57:31 +00001447- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001448 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001449 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001450 module will not be built.
1451
Tim Petersc17976e2006-04-01 00:26:53 +00001452- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1453 aren't officially supported here, and trying to use them will probably
1454 raise an exception some day. But dicts have been allowed, and "mostly
1455 worked", so support for them won't go away without warning.
1456
Georg Brandl338ef7d2006-03-31 18:42:16 +00001457- Bug #1445068: getpass.getpass() can now be given an explicit stream

1475
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001476- email 4.0 package now integrated. This is largely the same as the email 3.0
1477 package that was included in Python 2.3, except that PEP 8 module names are
1478 now used (e.g. mail.message instead of email.Message). The MIME classes
1479 have been moved to a subpackage (e.g. email.mime.text instead of
1480 email.MIMEText). The old names are still supported for now. Several
1481 deprecated Message methods have been removed and lots of bugs have been
1482 fixed. More details can be found in the email package documentation.

1485 (a subclass of tuple) that provides incremental decoders and encoders
1486 (a way to use stateful codecs without the stream API). Python functions
1487 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1488 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1489 have been added.

1570 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1571 Ronald L. Rivest offered this advice for Python:
1572
1573 "The consensus of researchers in this area (at least as
1574 expressed at the NIST Hash Function Workshop 10/31/05),
1575 is that SHA-256 is a good choice for the time being, but
1576 that research should continue, and other alternatives may
1577 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001578

1740 be exploited in various ways.
1741
Tim Peterse3547fd2005-12-16 23:13:57 +00001742- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001743 flags on the HTTP listening socket.
1744
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001745- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1746 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1747
Fred Drakefbdeaad2006-07-29 16:56:15 +00001748- Patches #893642, #1039083: add allow_none, encoding arguments to
1749 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001750
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001751- Bug #1110478: Revert os.environ.update to do putenv again.
1752
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001753- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1754
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001755- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1756
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001757- Enhancements to the csv module:
1758
1759 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001760 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001761 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001762 + Dialect parameter parsing has been re-implemented to improve error
1763 reporting.
1764 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1765 dictates.
1766 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001767 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001768 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001769 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1770 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001771 + reader now allows \r characters to be quoted (previously it only allowed
1772 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001773 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001774 + Dialect classes passed to the module are no longer instantiated by
1775 the module before being parsed (the former validation scheme required
1776 this, but the mechanism was unreliable).
1777 + The dialect registry now contains instances of the internal
1778 C-coded dialect type, rather than references to python objects.
1779 + the internal c-coded dialect type is now immutable.
1780 + register_dialect now accepts the same keyword dialect specifications
1781 as the reader and writer, allowing the user to register dialects
1782 without first creating a dialect class.
1783 + a configurable limit to the size of parsed fields has been added -
1784 previously, an unmatched quote character could result in the entire
1785 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001786 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001787 the parser field size limit (returning the former limit). The initial
1788 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001789 + A line_num attribute has been added to the reader object, which tracks
1790 the number of lines read from the source iterator. This is not
1791 the same as the number of records returned, as records can span
1792 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001793 + reader and writer objects were not being registered with the cyclic-GC.
1794 This has been fixed.
1795
Brett Cannone6539c42005-01-08 02:43:53 +00001796- _DummyThread objects in the threading module now delete self.__block that is
1797 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1798 lock primitives tend to be limited in number and thus should not be wasted on
1799 a _DummyThread object. Fixes bug #1089632.
1800
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001801- The imghdr module now detects Exif files.
1802
Raymond Hettinger6065d322004-12-20 23:51:53 +00001803- StringIO.truncate() now correctly adjusts the size attribute.
1804 (Bug #951915).
1805
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001806- locale.py now uses an updated locale alias table (built using
1807 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1808 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001809 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001810
Raymond Hettinger3557f422004-12-07 12:02:02 +00001811- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1812
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001813- the pickle module no longer accepts the deprecated None option in the
1814 args tuple returned by __reduce__().
1815
Brett Cannon84667c02004-12-07 03:25:18 +00001816- optparse now optionally imports gettext. This allows its use in setup.py.
1817
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001818- the pickle module no longer uses the deprecated bin parameter.
1819
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001820- the shelve module no longer uses the deprecated binary parameter.
1821
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001822- the pstats module no longer uses the deprecated ignore() method.
1823
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001824- the filecmp module no longer uses the deprecated use_statcache argument.
1825
Raymond Hettinger664347b2004-12-04 21:21:53 +00001826- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1827 extended or overridden by subclasses. Formerly, the subclassed method would
1828 be ignored by the rest of the module. (Bug #1078905).
1829
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001830- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001831 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001832
Walter Dörwald36733692004-12-22 12:50:50 +00001833- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1834 once when a size argument is given. This prevents a buffer overflow in the
1835 tokenizer with very long source lines.
1836
Barry Warsaw538561e2006-01-01 21:48:54 +00001837- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1838 immediately after creating the object, without any intervening
1839 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001840
Skip Montanaro05885812005-01-16 20:48:27 +00001841- The reconvert.quote function can now emit triple-quoted strings. The
1842 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001843
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001844- ``UserString.MutableString`` now supports negative indices in
1845 ``__setitem__`` and ``__delitem__``
1846
Greg Ward40407942005-03-05 02:53:17 +00001847- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1848 correctly.
1849
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001850- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1851 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1852 character even if the user has passed a size parameter to get a proper
1853 line ending. Remove the special handling of a "\r\n" that has been split
1854 between two lines.
1855
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001856- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1857 about illegal code points. The codec now supports PEP 293 style error
1858 handlers.
1859
Walter Dörwald78a78b02005-09-01 12:04:29 +00001860- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001861 from the input stream, so that the output is a byte string in the correct
1862 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001863
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001864- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1865 considering it exactly like a '*'.
1866
Walter Dörwald007f8df2005-10-09 19:42:27 +00001867- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1868 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001869
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001870- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1871
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001872- Patch #1413711: Certain patterns of differences were making difflib
1873 touch the recursion limit.
1874
Walter Dörwald58917a62006-03-31 15:26:22 +00001875- Bug #947906: An object oriented interface has been added to the calendar
1876 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001877 called as a script (e.g. via ``python -mcalendar``). Localized month and
1878 weekday names can be ouput (even if an exotic encoding is used) using
1879 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001880

1882-----
1883
Neal Norwitz602d3392006-03-31 08:21:40 +00001884- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1885 by using -mieee gcc option.
1886

1888
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001889- Build support for Win64-AMD64 was added.
1890
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001891- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1892
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001893- Patch #881820: look for openpty and forkpty also in libbsd.
1894
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001895- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1896 The zlib module is now builtin on Windows.
1897
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001898- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1899
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001900- Bug #1189330: configure did not correctly determine the necessary
1901 value of LINKCC if python was built with GCC 4.0.
1902
Trent Mick8321b422005-07-26 02:29:21 +00001903- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1904 vulnerability in zlib 1.2.1 and 1.2.2.
1905
Brett Cannon08cd5982005-04-24 22:26:38 +00001906- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1907 flags that change binary compatibility. Changes were also made to
1908 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001909 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001910
Bob Ippolitoed233462005-03-29 13:47:59 +00001911- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1912 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1913 no longer exists). This configure patch makes things right.
1914
Martin v. Löwise2713be2005-03-08 15:03:08 +00001915- Bug #1158607: Build with --disable-unicode again.
1916
Brett Cannon46d96232005-02-16 00:07:19 +00001917- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1918 defined. Discovered as a result of not being able to build on OS X.
1919
Brett Cannon516592f2004-12-07 00:42:59 +00001920- setup.py now uses the directories specified in LDFLAGS using the -L option
1921 and in CPPFLAGS using the -I option for adding library and include
1922 directories, respectively, for compiling extension modules against. This has
1923 led to the core being compiled using the values in CPPFLAGS. It also removes
1924 the need for the special-casing of both DarwinPorts and Fink for darwin since
1925 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1926 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1927 Fink, ``-I/opt/local/include`` for DarwinPorts).
1928
Brett Cannon43802422005-02-10 20:48:03 +00001929- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1930 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1931 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1932 Closes bug #1096244. Thanks Gregory Bond.
1933
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001934C API
1935-----
1936
Tim Petersc9d78aa2006-03-26 23:27:58 +00001937- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1938 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1939 is obtained via the ``PyObject_`` family, it must be released via the
1940 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1941 always been officially true, but when Python's small-object allocator was
1942 introduced, an attempt was made to cater to a few extension modules
1943 discovered at the time that obtained memory via ``PyObject_New`` but
1944 released it via ``PyMem_DEL``. It's years later, and if such code still
1945 exists it will fail now (probably with segfaults, but calling wrong
1946 low-level memory management functions can yield many symptoms).
1947
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001948- Added a C API for set and frozenset objects.
1949
Raymond Hettinger66517482004-12-03 11:45:13 +00001950- Removed PyRange_New().
1951
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001952- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1953 mapping argument now. This string is used as a mapping table. Byte values
1954 greater than the length of the string and 0xFFFE are treated as undefined
1955 mappings.
